AND National Traffic Safety Committee (NTSB) The alarm sounded during a press conference on Thursday, warning 30 owners of 68 bridges in 19 countries to implement vulnerability assessments to determine the risk of Bridge’s collapse due to the shipping of the ship.
The NTSB also quoted the lack of assessment of the state administration of Maryland, which may have prevented the deadly collapse of the Francis Scott Key Bridge in Baltimore.

NTSB Chairman Jennifer Homendy said that on Thursday, a key bridge is almost 30 times above the “acceptable risk threshold” for critical or important bridges, according to the instructions of the American Association of State Officials for Highway and Traffic (AASHTO).
Although the bridges not estimated to be sure they would collapse, the NTSB said: “He had Maryland transportation administration (MDTA) conducted an assessment of vulnerability on a key bridge based on the recent traffic of the vessel, MDTA would be aware that the key bridge was out of acceptable risk and that he would have information that it was proactively reducing the risk of collapse and loss of life associated with the bridge collision. “
“Honestly, we have sounded an alarm to this since the tragedy happened,” Homendy said. “We need an action. Public security depends on that.”

The NTSB has identified 68 bridges designed over the last year before the Aashto guidelines that have no current vulnerability assessment have been established.
NTSB recommends that 30 bridge owners estimate whether their bridges are above the acceptable risk level Aashto and, if so, develop and implement a comprehensive plan of reduction of risk.
Aashto developed and published a calculation of vulnerability assessment for new bridges on the 1991 National Highway System in response to NTSB research Sunshine Skyway bridge crashed in Florida.

At the time, Aashto also recommended that all bridges owners carry out a vulnerability assessment on existing bridges to “assess their risk of catastrophic collapse in the case of a vessel collision”.
Decades later, in 2009, Aashto reiterated that recommendation.
Since 1994, the Federal Highway Authority (FHWA) requires that the new bridges are designed to reduce the risk of the catastrophic collapse of the bridge from the crash collision, “given the size, speed, speed and other characteristics of the vessel moving through the canal below the bridge,” NTSB said.

Homendy added that NTSB also recommends FHWA, Us coastal guard The American Army’s engineering corpus also established an “interdisciplinary team” to provide guidelines and assistance to bridge owners in assessing and reducing risk.
Risk reduction can mean improvements of infrastructure or operational changes, according to NTSB.
NTSB will announce more than 1,000 pages of investigating material on public dokete on Thursday, including a bridge report and some interviews.

Next week, the NTSB intends to release dangerous materials, meteorological and survival factors of the factual reports and a study conducted by his naval engineering office on the size of the vessel and the related risk of safety.

The audio transcript and associate data recorder will follow, which will lead to the NTSB, which has published its final report, which is likely to happen in the fall.
MDTA did not immediately respond to the Fox News Digital request for comment on Thursday afternoon.
